Hubcentric rings are used to match the centerbore of the wheel to the hub diameter of the vehicle in instances where the two are not the same diameter. Hub centric rings allow the wheel to be more precisely centered on the hub which reduces the chance of vibration issues. Hub rings are inserted into the back of the wheel before the wheel is installed on the vehicle.
